Company

hirify.global develops supersonic aircraft, the Symphony engine for Overture, and Superpower industrial gas turbines for AI data centers.

What you will do

• Own steady-state and transient cycle modeling and operability analysis for Superpower and Symphony.
• Assess stall margin, starting behavior, transients, and load response with component and controls engineers.
• Define performance and operability test questions and instrumentation needs.
• Reduce test data, compare measured results with predictions, and calibrate models using evidence.
• Integrate compressor, turbine, combustion, and secondary-air trade studies into engine-level recommendations.
• Build reproducible, shared PyCycle models and engineering tools.

Requirements

• Aerothermodynamic fundamentals and experience in engine performance or operability.
• Hands-on experience with NPSS, PyCycle, GasTurb, or a comparable engine-analysis environment.
• Ability to explain component assumptions, maps, limits, and uncertainty behind cycle predictions.
• Experience with instrumentation, data reduction, testing, laboratory work, or model-to-data comparison.
• Python or equivalent for reproducible engineering analysis and clear technical communication.
• Must be a U.S. citizen, lawful permanent resident, protected individual, or eligible to obtain the authorizations required under ITAR and EAR regulations.

Nice to have

• Transient, starting, or sub-idle modeling experience.
• Experience with stall-margin stack-ups and design or controls trade-offs.
• Free-power-turbine or industrial-gas-turbine experience alongside aero-engine work, or the reverse.
• Experience building tested and documented engineering tools maintained by other engineers.

Culture & Benefits

• Work on engine-level design and test decisions for supersonic aviation and industrial gas turbines.
• Collaborate with compressor, turbine, combustion, secondary-air, controls, and test engineers.
• Flexible paid time off policy.
• Long-term incentives and equity may be available as part of the total rewards package.
• Applications are accepted on an ongoing basis while the search remains active.
